RECEIVER OR CATCH-BASIN.

SPECIFICATION forming part of Letters Patent No. 791,381, dated May 30,1905. Application filed June 2'], 1994. Serial N0. 214,251.

and exact description of the invention, such asv will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and. to figures ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in receivers or catch-basins, andmore particularly to that class designed for use in conducting to thesewers the surface water of streets.

The object of my invention is to provide an emergency-outlet which canbe instantly utilized in the event of a stoppage of the serviceoutletin. rapidly clearing the street of backedup surface water due to suchstoppage, such emergency-outlet also incidentally serving as a passagefor the introduction of a clearing instrument for removing anyobstruction in the pipe connecting the receiver with the sewer.

To these ends my invention consists of certain details of construction,all of which will be fully hereinafter described and claimed.

In the drawings, Figure 1 is a top plan view of my improved receiver.Fig. 2 is a vertical section taken in the line 00 m of Fig. 1. Fig. 3 isa partial vertical section taken in the line 3/ y of Fig. l, and Fig. 4is a view of the hook for manipulating the interior parts of thereceiver without removing the cover.

Referring tothe drawings, 1 is the body of the receiver, which ispreferably of elongated, square, or rectangular configuration withconcave bottom 2. Y

side a vertical linepassing through the exten sion 6. This position ofthe pivot-points 8 8 in the side walls of the receiver causes the hooks7 to remain in engagement with the extensions 6 under the action oftheir own weight, which will effectually prevent any accidentalunseating of the cover. To remove such cover when necessary, thehand-hook 9 (see Fig. 4:) is passed down through an adjacent opening 5,and with such hook 9 the pivoted hooks '7 can be thrown over against thepins 10 on the walls of the receiver, thus disengaging such cover forremoval. The cover may be again locked by the hand-hook 9 operatingthrough the openings 5, as before.

10 is the service outlet-orifice, opening into the attached outlet-pipe11, which is first curved upwardlyas it leaves the outlet-orifice 10 andthen downwardly to communicate with the sewer.

It will be seen that the highest point 12 in the floor of theoutlet-pipe 11 is above the level of the outlet-orifice 10. This causesthe level of the standing water in the receiver to remain above suchoutlet-orifice 10,thus forming a water seal or trap to prevent thesewergas from backing up into the receiver.

13 is the emergency-outlet in the wall of the receiver, opening into thestraight outletpipe 1 1, which extends. down at an angle to andintothe'service outletpipe 11, as, shown. This pipe 1 1 is arrangedpractically in line with pipe 11 at its entrance-point, thus making itan easy matter for the insertion of a clearing instrument, such as aflexible ash strip, down through the pipe 1 1 and into pipe 11 in thedirection of the main sewer for removing any obstruction in the pipe 11beyond its junction with pipe 14. This provision for clearing pipe 11 isextremely valuable and forms an important adjunct to my improvedconstruction.

15 is a gate for closing the emergency outlet-orifice 13 when not inuse. It slides snugly into position in the frame 16 and can be raisedout of such frame to open the emergency-outlet by means of the hand-hook9 through an adjacent opening 5 in the cover. The lug 17 at the top ofgate 15 is for engagement with the hand-hook 9 in removing such gate andrestoring it to its closing position. The chain 18, attached to the gate15 and to the wall of the receiver, facilitates its restoration to theframe 16.

The emergency-outlet above outlined is for use when the serviceoutlet-orifice 10- has become clogged with debris to such 'an extentthat the flow of water to the sewer is checked or stopped entirely.

A quick release of the rapidly-accumulating surface water is oftenhighly important. This can be instantly effected by pulling out the gate15 and permitting the surface water to flow off through theemergency-outlet, after which the obstructing debris can be removed fromaround the service outlet-orifice 10 at a more convenient time.

I elaim The combination with a receiver, of the service outlet-pipe 11,curved upwardly from its point of attachment with the receiver and thendownwardly to the sewer, the straight emergency outlet-pipe l4communicating at its upper end with the emergency outlet-orifice 13 andat its lower end with the service outlet-pipe 11, at a point without thereceiver, at the beginning of the downwardly-cnrved portion of theservice-outlet, the straight emergency outlet-pipe 14 being arranged inline with the downwardly-tnrned portion of the service outlet-pipe 11and the sliding gate 15 for closing the emergency outlet-orifice 13,substantially as and for the purpose stated.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN M. THOMPSON.
